- To all whom, it may concern:

' described and claimed, of the drawing-cones and the dies, the latter beingimmersed in a lubricant and the former being arranged outside the lubricating trough and provided with separate cooling arrangement. The abundant lubrication of the.dies thus insured allows of greater speed in the working of the machine, and the splashing of the lubricating liquid by the cones is obviated.

In the accompanying drawings the invention is illustrated, Figure 1 representing a perspective view of the machine, Fig. 2 a front view, partly insection, of the mainparts of the machine and Fig; 3 a sectional side view of the same. Fig. 4: is a diagrammatic view showing how the wire is wound through the dies and around the cones.

The machine consists of a frame 5 in which a driving shaft 6 is mounted, said shaft being fitted with bevel gears 7 and' 8 for rotating transversely arranged inclined shafts 9 and 10 respectively. The latter shafts carry the drawing cones b and '6 A trough 3 is connected to the machine 'frame for the reception of the lubricating liquid. In this trough the die holder 0; is arranged and so is a series of guide rollers 4 which guide the wires from the cones through the liquid to the dies.

The dies 2 are fitted in the holder a in such a manner that, while their apertures are in the same horizontal plane CD (Fig. 3), the dies themselves are set in an inclined plane AB (Fig. 2). The dies are held in the lubricant, and the holder may be adjusted for immersing them more or less into the liquid. In conformity with this arrangement of the dies, the stepped drawing cones b and b are mounted with their shafts over the trough so that the points 9 g g where the wires contact with the cone-grooves, are all disposed, in a plane EF (Fig. 2,)' this plane being perpendicular to the plane AB and to the die-apertures. The threading of the wirethrough ment of the cone, since it is easier to wind thewlre around .aninclined element than around a horizontal-one. only one cone aPatented July 2, i912.

N-the machine is facilitated by this arrange need be employed, but to avoid the emplo yment of a very lon'g a-nd bulky cohe,when

a great many drawings are required, the ar-- ran'gement may be as shown'ln'the figures where two small cones Offtlllfll size are employed, the second cone being driven at a greater speed so that the wire can be passed from the largest step of thefirst cone over a guide-roller 4 to the; smallest step of the second cone and the drawing continued by the latter. The ready-drawn wire is wound on a drum c which, accordin to the invention, is mounted, as shown in the figures,

on the second cone 12 an easy removal of the wire-bundle being thereby insured.

Owing to'the abundant lubrication Qf' tl1.

dies effected by the arrangement, the machine can be driven at an accelerated speed.

The increased speed, however causes the first cone to be greatly heated by'the thick wire running thereon. To counteract this heating a cooling arrangement is provided in which the employment of packing boxes is entirely avoided. The hollow cone 7) is closed at its front end by a disk is having a circular opening in its center. Through this opening two stationary pipes Z and mare introduced into the cone for the supply and discharge of cooling liquid. Z is the supply pipe and is made considerably narrower than the pipe m which is the discharge pipe. innermost partof the hollow cone for feeding the liquid to this part. The pipe m is formed with a curved-(Fig. 2) carried revers'ely to the rotating direction of the cone and terminates, with its flared nozzle 0, about one quarter of an inch from the'disk The pipe 1 is carried to the 7c and from the cone-wall at the deepest porcharged by the pipe m. To prevent the.

liquid from flowing along the outer surface of the pipe m through the vopening in the disk is, the curve 1' is bent to form a sack,
